SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 355,835, dated January All, 1887.

Application filed June 9, 1886.

To @ZZ whom it may concern:

Be it known that I, GEORGE H. NOBLE, a citizen of the United States, residing at Lowell, in the county ot Middlesex and Coxnrnou wealth of Massachusetts, have invented a certain new and useful Improvement in VindoW- Sash Holders, of which thefollowing is a speciication.

My invention relates to window-sash holders 5 and it consistsin the devices and combinations hereinafter described and claimed.

In the accompanying drawings, Figure l is an isometric view of a part of a window-jamb, inside bead, parting-bead, outside bead, and a part of the upper sash, and a part of the lower sash adjacent to said jarnb; Fig. 2, an inside elevation of adjacent parts of the upper sash and the lower sash, and a vertical transverse section of a part of the jamb and adjacent wall iiush with the inner face o1. the lower sash; Fig. 3, a vertical central section of the socket and sleeve, and a side elevation of the roller, stock, spring, and tension-plug; Fig. 4, a plan ofthe holder detached. Fig. 5 shows a modification of the holder, a non-rotary block being substituted for the roller.

Myimproved holder consists of a socket, S, of the forni shown, provided at its lower side edges with longitudinal ears s, having screwholes s', through which screws s2 are driven vertically into the top rail of the lower sash, WV, or vertically upward into the bottoni rail of the upper sash, XV. Vithin the socket S is placed the shank t of the stock T, the prot', between the tines of which, on a horizontal axle, of, turns a roll, Rpreferably of hard wood, as box-wood. In use the roll E bears against the jarnb J, between t-he parting-bead, I and the inside bead, l', it the holder is attached to the lower sash, and `between the parting-bead and the outside bead, I2, if the holder is applied to the upper sash. The shank t of the stock T is surroundedV by a spiral spring, O, which is compressed between a shoulder, t2, on said shank and the end of a sleeve, D, which surrounds the end of the shank, the spring crowding the roll R against the jalnb. The sleeve D is large enough to slide freely on the shank t, and is crowded against the inner end of the spring O byaten- .low of such contact.

sion-plug, l?, provided with a screw-thread,p,

which engages with an internal screw-thread, s, formedv in the inner end ofthe socket S. The sleeve D is long enough to reach for some distance beyond the inner end ot' the shank t. The tension-plug is provided with a slot, 10', into which the blade of ascrew-driver may be introduced to turn said plug and force said sleeve against the spring to increase the tension of the spring and the pressure of the roll upon the jamb.

The stock T is prevented from being thrown out of the socket S when the holder is not in use by a downward projection, t, with which said stock is provided, and which'reaches nearly through the slotted under side of the socke't S, the under side of said socket being slotted or open, except near the ends, as shown at 85 in Fig. 3, the bar s", which closes .the front end of the slot e5, acting as a stop to receive the thrust of the projection t3.

Vhen the holder above described is applied to the window-sash, it should be so'applied that the outer end of the socket or bar s* shall be n`ear enough to the jalnb `to hold the projection t3 out of contact with the outer edge of the bar s, and at such a distance from said bar that any inequalities oi` the janib will not al- It will be much easier to apply the holder it the plug P is first loosened. It will be better to use two holders for each sash at oppositeends of the same rail, and of course turned in opposite directions to bring the rolls outward against the janibs.

1 The holder above described is capable,when applied as above described, of holding awindow-sash at any desired height without the use of balancing-weights and sash-cords.

The modification shown in Fig. 5 is applied and used as above described, and its construction is the same as theholder above described, except that, instead of the roll R, a block, R', is used, it being supported in the forked end of the stock T, j ust as the roll It is supported. The block It is preferably triangularin crosssection, -one of its tlat sides bearing against the jamb, just as the face of the roller is rep resented as bearing against said jainb in Fig. 2, and operates to hold thev sash at any desired height,'just as the roll It does, by frictional contact with the jamb. The roll is preferred as holding the sash with sufficient firmness and opposing less resistance to the raising or IOO lowering of the sash in the ordinary manner when desired, the roll or block remaining in contact with the j amb during such raising and lowering.

The plug l? may be entirely removed from the holder while the same is being secured to y v the sash, and the sleevervbe allowed to project through the plug-hole during the operation. After the holder is secured to the sash the sleeve may be crowded back into the holder by the point of a screw-driver7 and retained therein by a pin inserted in the hole S5, and reaching into the holder back of said sleeve until the plug can be replaced.

I am aware that a sash-supporter consisting of a forked plunger carrying an anti-friction roll and having a shank surrounded by a case has been applied to the j amb of a window-ease, the plunger being forced outward by a spring contained within said ease7 to press said roll against the side of a window-sash; but such an arrangement renders it necessary to remove the windowsash while the supporter is being applied to the jamb, unless the verticaltraverse of the sash is greater than the length of the sash. In the supporter referred to the only means of Varying the pressure of the roll upon the sash is by turning the case7 which is externally screw-threaded in the hole which receives said case.

I claim as my invention- The combination of the socket adapted to nbe attached to the rail of a window-sash, a stock having ashank placed within said socket and provided with a fork, a roll or block supported in said fork, a spring surrounding said shank within said socket and `compressed be-
